New here, after some help. Just done the classic of breaking the cover of the rear light assembly only to find you need to buy a whole unit to replace the plastic cover. Two questions: 1) Is it at all possible to buy and replace the plastic cover? 2) If not, how easy is it to replace myself if I buy a replacement complete assembly - i.e. unscrew bolts, connect wiring up etc.? Any help greatly appreciated.....
